IMPROVEMENT IN END-GATES FOR DUMPlNG-CARTS.

Specication forming part of Letters Patent No. 152,433, dated June 23,1874 application tiled May 13, 1874.

To all whom it may concern Be it known that I, J oHN SWEENEY, ofManchester, of the county of Hillsborough and State of New Hampshire,have invented a new and useful Improvement in Tip-Carts; and do herebydeclare the same to be fully described in the following specification,and represented in the accompanying drawings, of which- Figure lis a topView, Fig. 2 a rearend view, and Fig. 3 a side elevation, of a tip-cartprovided with my invention, the wheels not being represented.

The invention consists mainly in the combination, with the cart-body andits tail-board, of a mechanism by which, while the body may be in theact of being dumped7 or turned down on the axle, the rear end of theeartbody shall be opened to discharge the contents of the body, theclosing of the said end taking place by and during the counter movementof the body.

In the drawings, A denotes the tip-cart body, made in the usual manner,and provided at its rear or open end with a taihboard or cover, B. Thethill-frame C is shown as projecting in front of the axle D in the usualway, the body being hinged to the axle. From the thill-frame ltwo arms,a a, project backward, as shown,

tailboard. Furthermore, from the forward pivot c of each of said linksone of two curved guides or rods, d, is extended through one of twoinclined and hooked arms, e e, projecting upward from the arms a a, inmanner as shown, cach rod d being also pivoted to the tail-board at itsend, and near its lower edge. The pivots are shown at f j'. Each of thearms e eis hooked around its guide-rod d, which rests upon a pin, g,going through the hook.

On tipping' the cart-body, the tail-board will be held up so as touncover the rear end ot' the body, the connection-links b b beingpreserved in, or about in, parallelism with the arms a a. During thereverse motion of the body, it will be moved up to the tail-board and beclosed thereby. Thus the tail-board will be automatically operated,while the body may be in the act of being turned cit-her upward ordownward, the whole saving the necessity of the usual manualmanipulating of the tailboard to open the cart-body at its rear end, inorder that the earth or contents of Athe body may be discharged from it,and to subsequently close it.

I claiml In combination with the tail-board, the tipcart body and itssupporting-frame, the arms a te e, the links b b, and the guide-rods dd, to operate as set forth.

JOHN SWEENEY.
